THE IMPORTANCE OF COMPUTER-BASED TESTS (CBT) IN SCHOOLS


The Computer Based Test has been adopted by most universities in the country as a result of its effectiveness and efficiency. Before this development, the Paper Pencil Test (PPT) was formally adopted by schools for examinations. Albeit, CBT is now used for examinations and Examination Boards like JAMB and others use it to deal with large scale examinations. 


Interestingly, PPT was also a good idea at the time, computer-based tests have been flying high and making waves as a better idea currently for examinations. With the computer-based test, you can be at a distant location and still sit for your exams. Less stress and a more integrated process for students and examiners alike.  


Moreover, its speed in marking and grading an individual’s result as well as its efficiency in collating results for easy documentation has proven to be superior to human grading and PPT with little margin for error. There is no delay; rather it comes from the programmers correcting their errors and giving out the results timely. 


On one hand, CBT does not work with emotions which enables it to eradicate human failure. Examiners might be swayed by external forces and their emotions or stress from marking hundreds to thousands of scripts. Nevertheless, this gives each candidate the same opportunity. Although, examiners could set questions types and even shuffle questions to reduce examination malpractice and keep things fresh.


On the other hand, there's strict time control. Once the time is up for a candidate, it automatically saves the work and goes off until another candidate logs in. This saves time for more people to sit for their exams and allows for more exams to be done. An error could only occur if there are: electrical problems, a limited time frame for complex examinations or the system has a problem. 


In general, CBT does not have a case of missing scripts. Once the system logs you in, you’ve automatically been marked present for the examination and the result will be provided. If there is a problem, it either comes from the candidate missing a process required or from the programme. 


Furthermore, CBT has helped a lot of universities with setting questions, marking and grading general courses and special electives which are being offered by numerous students. Though CBT has helped in numerous ways, it's still limited: to objective questions, by the unavailability and inaccessibility of computer systems, by computer savvy, and some exams require specific and special works especially practical courses. 


In conclusion, CBT has pushed the horizon of examination procedures and education. However, there are still problems that individual institutions need to solve. Nonetheless, CBT has shown that it is possible to change the way things are done in schools and it is promising to see what will be done with it in the future. Probably, CBT will be able to reach new heights and more complex examinations will be done. All in all, CBT promises efficiency, effectiveness, speed and seamlessness.

By  Adetunji Oluwafemi The Great Ife Students’ Union on Monday, 3rd November 2024, held its planned inter-faculty debate for freshmen. The debate is part of the events that have been prepared for Fresher’s Week 2024. The event experienced a slight delay, as the venue was moved from the 1000-seater to Oduduwa Hall by the order of the school management, which requested that the initial venue be vacated because the office of the Vice President, responsible for the event, failed to seek permission before using it.

MOREMI HALL: A Tale of Night Stories: When Will It End? In the quiet corridors of Moremi Hall, a disturbing series of events has shaken the residents, raising questions about security and the unknown intentions of an elusive intruder.   It all started two weeks ago when the inhabitants of Moremi Hall were awoken to the cry of a lady, "Ole! Ole! (the Yoruba name for thief). At exactly 5:00 am, a guy who was wearing a mask was seen darting across the corridors. He was said to have stolen phones, and while he tried to escape, he was seen by some ladies who raised the alarm.   An eyewitness who will like to remain anonymous said he ran out of the kitchen and jumped down from the second floor to the ground. He sustained minor injuries, and to reduce the chase, he let go of the phones, which he had put in black nylon.   The Moremi residents were able to recover their phones, but he escaped through a gutter, and no one knows where he went. The porters were informed i...
